A simple function to compose an arbitrary number of functions from right to left, or left to right.
npm install --save fn-compose
var compose = require('fn-compose'),
mul2 = function mul2(a){ return a * 2 },
sub1 = function sub1(a){ return a - 1 },
mul2Sub1 = compose(sub1, mul2);
mul2Sub1(5); //=> 9
There is also a left to right mode, which is exported as ltr:
var compose = require('fn-compose').ltr, // Notice the .ltr
mul2 = function mul2(a){ return a * 2 },
sub1 = function sub1(a){ return a - 1 },
mul2Sub1 = compose(sub1, mul2);
mul2Sub1(5); //=> 8
